SEAL AND SPOUT FOR CANS AND OTHER RECEPTACLES.

Specification of Letters Patent.

Patented Dec. '7, 1909.

Application filed January 7, 1909. Serial No. 471,172.

To all whom it may concern:

Be it known that I, HARRY A. Tnnnsoann, a citizen of the United States, residing at 431 Main street, Conneaut, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Seals and Spouts for Cans and other Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement on Letters Patent to applicant No. 807,223, although not in all respects exclusively confined to the construction shown therein. Its chief object is to provide for cutting off or permitting the flow of liquid through the can neck'and the spout, by turning the lat ter into one position or another, the cap having an opening formed for this purpose, which registers with a similar opening in a plate belonging to the spout. To this end I employ the construction and combination of parts hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1 represents a perspective view of the upper part of the can and its neck, Fig. 2, a vertical section through said neck, the cap, the spout and the outer cap, on a larger scale, and Figs. 3, 4, 5 and 6 represent detail views of the several parts.

A designates the tubular can-neck, which is of the ordinary screw-neck type and may be used with a square can or any other OICl1 nary form of can as well as with the round can herein partly shown. The material of the can also is unimportant and the word can isused in this specification as meaning any scalable receptacle for liquid or other fluid substances. Said neck has an upwardly and inwardly tapered or reduced central part A terminating in a rounded head a constituting the rim of said neck and formed by rolling its edge outward and downward.

B designates the inner cap, which is provided with an annular flange b as in the case of said patent, which flange is flexible and thus adapted to be pinched or crimped in around said head to hold said cap in place. In said patent the top of said cap was a flat disk descending considerably within said screw-neck and extending across the same at the lower end of the tapered part A. In the present instance the middle of this central part of said cap is struck up to a level with the rim of said cap or very slightly above the same, forming a flat disk or circular plate 13, having therein an opening B on one side of the center and surrounded by a circular trough I) separating the raised exterior wall of said cap from the circular supporting wall of said struck-up disk thus perforated. The opening B pcrinits the outflow of fluid when it is not covered. All parts of this cap are integral.

C designates a horizontal outlet spout, having at its attached end a base plate D, adapted to fit and turn on said disk and provided with an opening D which registers with said opening 13 and communicates with the inner end of the horizontal passage of said spout, entering the same from below at right angles.

E designates an external cap or cover, screw threaded in its circular side wall to engage the screw thread of neck A; also provided with a central circular opening E in its top, through which said spout may be passed from below in fitting those parts to gether; and having furthermore a horizontal flange or exterior annular part E overlapping the outer part of plate D and holding it securely against said disk and the upper end or rim of the neck when said outer cap is thus screwed in place, but allowing said spout to be readily turned for cut ting OK or permitting the flow of liquid through said spout according to the position of rotation of the latter.

The lower face of plate D is provided with a recess d, which is filled with a rubber or other suitable packing F, through which the opening D is extended. This packing insures tightness of joint around said opening and will make the cutting off of the flow absolute when the spout is turned so that said openings D and B are no longer opposite each other. Said spout is provided with a small vent e in the to of its inner end its passage at this end being extended inward beyond said opening D Vt hen the spout is turned so as to cut oif the flow the cam is ready for transportation and when there is need to pour out the liquid it is only necessary to turn the spout into the proper position therefor and the cam is ready for use.

The term rotatable, as used in the claims, is not intended to involve the necessity of complete rotation, for a very much less amount of rotary movement will sulliee. The term ran-neck in said claims is intended to apply to a screw-neck such as shown or to any other form of raised neck constituting an inlet or outlet. The [)fllllFttltlL form shown is made to serve as an inlet by removing both caps, or the lower cap may be left in place and the neck of a funnel directed into the opening 15*. hen the liquid is to be poured out all the parts hereinbefore described are in place, the spout aforesaid being turned so as to extend over the side of the can. hen a square can is used, the neck, spout and cap are preferably located in or near one of the corners of the top, for greater convenience in pouring. hen the spout is in this position, the openings 13 and D are opposite each other, so that there is no impediment to the flow of liquid. The

operation of cutting olf this flow by turning back the spout over the body of the can has already been described. This sort of a closure requires no cement and no packing except the small disk of the latter material marked F and set into a. recess of plates D as above described. Even this packing is not absolutely necessary though very desirable.

The operations of preparing the can for pouring and sealing it for shipment or to stand closed until there is need to pour again are reduced to the least possible terms in work and time. bined closing and pouring devices are very easily made from sheet metal, although not necessarily confined to that material, and. involve very little expenditure in manufacture. The particular method of holding the spoutwhieh I have shown is of course not indispensable, though preferred to any other, which will secure it while allowing the necessary rotary movement for opening and closing. The means of fastening the cap B to the neck A in accordance with my previous patent. herinbefore mentioned is also preferred, but of course the spout and outer cap might be used with the inner or lower cap B, even if the latter did not have any part pinched in under the bead at the rim of the neck, or even if it were left wholly unfastened except by the engagement of the outer cap E with the screwthreads of the neck; but in this last case it would be hardly practicable to insure perfect register of the openings l3 and D for permitting the pouring of the liquid at the proper time and in a proper way or cutting it off properly. On all accounts we greatly prefer the construction shown to any other.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A can-neck having a cap provided with a. perforation, in comblnation with a device The parts of the eomreinovably attached to said neck and provid d with an opening above said cap and a spout adapted to be passed through said opening, but provided with a part. which cannot pass through the same, the said spout and part being removable from said device and also being rotatably adjustable on said cap to open or close the passage through the same, substantially as set. forth.

:5. A can neck which externally screwthreaded and provided with a cap having a. a-rl'orat ion, in combination with an annular part which is screw-threaded to engage said nrek and provided. with a central opening and a horizontal part surrounding the same, a spout adapted to pass up through the said opening and removable from said annular part at will, said spout being provided with a. plate extending under said part and said spout and plate being free to be turned in contact with said cap to open or close the latter.

3. In combination with a. can neck having a cap provided with a perforation, a spout; normally adjustable by rotation thereon, provided with an opening which registers with said perforation, said spout being adapted to close the can by turning said opening out of register therewith, and means adapted to be detachably fastened on the can and to hold said spout on said cap, but permitting the said spout to be withdrawn from said means after detaching the latter from the can, substantially as set forth.

a. In combination with a can neck provided with a. cap B having a perforation, a. movably horizontal spout having an opening in its under side adapted to register with said perforation and provided with a. recessed plate containing a packing which is correspondingly perforated, said plate eX- tending outward from said recess and a screw-threaded, additional cap E adapted to engage the screw-threads on said neck and to overlap the outer part of said plate for holding said packing against cap B and said spent in place, said cap E also having a central opening through which said spout may be withdrawn at will after removing cap E from the can neck, substantially as set forth.

A can neck in combination with two caps fastened thereon and a spout, which has a part clamped between these caps and is removable from the upper cap, said caps and spout being provided with registering perforations and said spout being rotatably adjustable while in position against the inner cap to open or cut off the flow through said perforations at will.

6. A. can cap B having a raised central perforated flat disk, a trough surrounding the same and an outer flange for fastening said cap in place, in combination with a second cap E, detachably fastened over the first cap and having a central opening and a spout which is removable at will from cap E through said opening and provided with a plate whereby the on p 1) holds the said spout in position on up B, said spout communicating with the opening in the latter or 0105 ing it, according to tho position into which it iR iiirlicd.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
